How to make the root go deeper

There is one writing on “Snooth” which talks about dry farming. It is said “dry farmed develop root systems that insulate them from many of the vagaries associated with inconsistent rainfall, so they generally produce more successful wines in times of either drought or excessive rainfall. “

The result of wine can have more mineral note which expresses the terrior.

I further think about the earth structure.

If the fog, the wind from nearby ocean or lake, river can bring some humidity to the vines;

if the vine are planted very closely, the vines gonna complete for water and would go deeper as a result of failure from growing around;

and if the sunshine at daytime and chill at night would also encourage the root to go deeper;

we still need something to bring about water.

As the water is also a contributor to make a fruity wine, together with sunshine, without irrigation, the dry farming shall sometime give the vines a shade to the burning sunshine, such as hays as a shield. and shall grower loosen the earth a little bit; or cut the new twigs a little bit; canopy management; we may need to talk about this further in the future…
